Get to Know Us Horizon3.ai http://Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants.

What You’ll Do We are hiring a Principal Backend Engineer to serve as the Technical Lead for the Risk Based Exposure Management (RBEM) team. You’ll be responsible for shaping the systems, architecture, and technical direction behind a product that helps security teams cut through the noise and prioritize actually fixing the weaknesses that represent real risk in their environment. This role is for a senior individual contributor who leads through technical judgment, cross-functional partnership, and execution. The right candidate will be equally comfortable translating ambiguous product goals into concrete technical roadmaps, writing production code (primarily backend but with an understanding for frontend as well), mentoring other engineers, and influencing decisions across multiple projects and partner teams. Successful candidates will be product minded engineers with an obsession for the details and customer outcomes. As a Principal engineer, you will help shape longer-term technical direction with broader company impact and influence beyond a single domain. In the short-term this role will split time 50/50 between hands-on coding and architectural design.
